BADIOCLOCK.

Application filed September 23, 1927. Serial 170. 221,510.

The present invention relates to an improved radio clock and it has more particular reference to a structure of this class which embodies an alarm clock work in which a novel and dependable electric circuit make and break device is incorporated.

Briefly, the invention comprises a clockwork such as is employed in the construction of ordinary alarm clocks, means whereby it can be mounted upon the radio cabinet in such a way as to render it accessible in order that the hands on the main dial can be set or the alarm set to go off at a predetermined time.

Associated with the rotary alarm shaft is an' electric circuit maker and breaker of a manually controlled type which may be regulated to cause the radio set to automatically start at a predetermined time, or to stop when desired. Thus, a definite program can be had whenever desired. 7

My principal aim is to provide a mechan-ism of this character which is so constructed as to permit it to be incorporated in the or dinary clockwork without requiring alteration of any of the existing parts, with the exception of removing the impact element and signal and substituting for the impact element, a rotary device including manually regulated make and break pins.

Other advantages can better be appreciated after reading the following description and I the accompanying drawings.

In the drawings I Figure 1 is a fragmentary front elevational view of a portion of the cabinet showing the radio clock mounted therein.

Fig. 2 is a horizontal section through the cabinet, looking on top of'the complete str ucto ture as it appears inside of the cabinet.

Fig. 3 is a side elevational view of the clock work-removed from the cabinet. 1

Fig. 4 is a view showing the stationary current supply brush.

Fig. 5 is a perspective view of certain of the details.

As before indicated, I employ an ordinary clockwork such as is used in the construction of a conventional alarm clock. and in the drawings, I have designated the frame of this clock work by the reference character 6. p In carrying out the invention, this frame is suitably mounted upon a swingable closure 7 (see Fig. 2), this closure being hin edly mounted upon the radio cabinet 8. t 18 equipped with the customary main dial with WhlCh the usual hands cooperate and with a supplemental dial indicated at 9 in Fig. 1, with which the alarm pointer cooperates.

In Fig. 2, the reference character 10 designates the key for winding the sprin while the reference character 11 designates t e long stem for setting the alarm. The only parts of the alarm to be specifically mentioned here, are the usual flat spring 12 (see Fig. 3) and the rotary shaft 13. In practice, this shaft carries an impact element, which cooperates with the signal. These parts are removed however, and the present invention is substituted therefor. As shown in Figs. 2 and 3, a brass disk 14 is fastened to one endof the rotary. alarm shaft 13, and is insulated from this shaft by insulating rings 15. At the center of this disk, is a post 16 upon which a. rocker arm 17 1s pivotally mounted. The rocker arm carries a pair of independent contact members in the form of pins 18 and 19, these pins working through holes in the brass disk 14. It will be noticed however, that the pin-19 is provided on its lower end with an insulating head 20.

With this arrangement, either one of the pins 18 or 19 may be forced down through the opening in the disk. Closely associated with the rotary pin equipped disk is a novel trip device. This device is shown in detail in Fig. 5, and its position in the clock work is better shown in Fig. 3.

As represented in the last-named figure, it comprises a longitudinally shiftable rod 21 carrying a right angularly disposed arm 22 at one end. Incidentally, this arm 22 is of insulation material and on its extremity, it is provided with a right angularly extending pin 23 which cooperates with either one of the aforesaid pins 18 and 19.

Also carried by the rod 21, is an actuator 24 of right angular form. The long leg of this actuator extends through an opening in the frame of the clock and bears upon the aforesaid flat spring '12. Thus, the.inside trip device comprising the parts 21, 22, 23 and 24, is movable as a unit in the frame of the clock toward and from the pins18 and 19. In connection with these-parts, it will be noticed that a wire 25 is electrically connected with the 'pin 23 (see Fig. 4). Also as shown in Fig. 4, a current supply brush is provided.

This brush comprises a socket 26 having a under or along the insulated base 30. The

3 to the time desired to start the radio.

positive wire from the storage battery is connected to post 28. Then the positive storage wire of the set is connected to post 31.

In considering the operation, it is to be assumed for example, that the pins 18 and 19, are occupying the position shown in Fig. 2. At this time, insulation head on the pin 19, which is then pushed-out, is resting against the short pin 23 of the so-called trip device. Thus the circuit is broken, even when the radio switch is turned on. Now the alarm handscan be set in a customary manner Incidentally, when the alarm hand is thus set the entire trip device, will be moved in a direction toward the disk 14, sliding the short pin 23 against the edge of the insulator head 20. Next, the rocker arm 15 is actuated so that the right hand end in Fig. 2 is pushed down and the left hand end pushed out in the opposite direction. This causes the parts to assume a relationship just reverse to that represented in Fig. 2. This movement of the pin 19 however does not disengage it from the pin 23.

When the hands of the clock reach the designations on the dial corresponding with that of the alarm pointer, as is usual, the alarm mechanism in the clock work causes the flat spring 12 to move in a direction away from the frame 6. In this connection, it is to be stated that persons familiar with the operation of the alarm mechanism will understand that in one position, the spring 12 is substantially in contact with the frame of the clockwork, while when the alarm, ordinarily goes ofi', this sprin moves in a direction away'from the frame.- hus since the spring is connected with the tripdevice, of this invention, it will cause this trip device to shift longitudinally, thus actuating the pin 23. In other words, the pin 23 will at one time be moved up or toward the disk 14 while at the time the alarm would go (if, it moves in a direction away from it.

When it moves in the last-named manner, it allows the insulator head 20 to clearthe pin 23. Now, the'alarmshaft 13 will rotate in the customary way under the action of the spring,

turning the disk 14 to anfapproximate half revolution. It is remembered, however, that i the pin 18 is now pushed toward the disk 14 as far as possible. Hence, it comes into enga emcnt with the pin 23.

ince the pin 18 is not insulated from the pin 23, the circuit is thus closed. Also since the radio switch is already on, it is obvious that the radio will start at the time which the alarm was previously set. Just the reverse is true if we had started with the pin 18 in engagement with the pin'23, instead of an engagement between the pin 19 and 23 as shown in Fig. 2. i

For example, to assume that pin 18has engaged the in 23, instead of the pin 19, inFig. 2. Then the pin 19, would have been pushed outwardly to hold the pin 18 in an opposite direction, and as soon as the alarm would off, the pin 18 would clear the pin 23 and t e disk 1 1 would rotate a half revolution to bring pin 19 against the pin 23 and to open the circuit again, thus stopping the radio at a certain time.

It is of course obvious that by controlling the usual switch on the radio, this auxiliary time controlled switch can be thrown out of operation. v The advantages, and construction and operation of the inventionwill be clear after considering the description in connection with the drawings. Therefore, a more lengthy description is believed unnecessary.

Minorcha-nges in shape, size, and rearrangement of parts coming within the field of invention claimed my be resorted to if desired.

Having thus described-my invention, what I claim as new is I y 1.
